2-port 10Gbps USB C PCIe Card - USB 3.1 Gen 2 Type-C PCI Express Host Controller Add-On
Card - Expansion Card - USB 3.2 Gen 2x1 PCIe Adapter 15W/port - Windows, macOS, Linux
Product ID: PEXUSB312C3
This PCIe USB 3.1 Gen 2 card installs into an available PCI-Express slot in your computer and enables you to
upgrade your current system by adding two USB-C (10Gbps) ports.
Also known as USB 3.2 Gen 2x1, this USB 3.1 Gen 2 card adds two 10Gbps USB Type-C ports to your computer.
Utilizing an ASMedia ASM3142 chipset, this card harnesses the speed of USB 3.1 Gen 2. With higher data
throughput support, this USB 3.1 Gen 2 PCIe expansion card is a necessity for external drives and many other USB
3.1 Gen 2 peripherals and includes an optional SATA power connector for high power devices.
The card is backward compatible with USB 3.0 (5Gbps) and USB 2.0 (480mbps) devices. The card works with newer
USB-C devices, but can easily support your existing USB-A peripherals using inexpensive USB Type C cables and
adapters. See our Accessories Tab for supported options.
The USB 3.1 card is compatible with Windows, Linux and macOS operating systems. The card includes both
standard-profile and low-profile brackets to install in various form-factor PCs and servers.
